I disagree with the allegation of 'fraud'.

What is the 'intent' by the customer 'signing up' to a Promo ?

The customer 'intends' to stay at the company properties ( whether or not they are independently owned ).

'Fraud' is where there is 'intent' to steal or otherwise obtain goods or services without paying, or by financial deceit ( eg. passing worthless cheques ).

There can be no evidence of such an allegation, simply by virtue of the Company allegation of 'you weren't targeted' for one or more promos.

I admit, that I've gone through this. I think it depends on your account status at the time. Eg. RA ? AMB ? Plat ? Number of points in account ?

Having said that, I didn't receive the email the OP received. I simply got the 'error' at log in ( for a month ). I rang them ( 3 -4 times ). Eventually, they fully re-instated me. They referred to an 'infamous' promotional competition - where quite a number of account holders 'entered' too many times.

The argument has been, that if the 'system' allows you enter a promo, then the promoter MUST accept a degree of responsibility ... and THAT negates any reasonable potential allegation of 'fraud' on the part of the customer.
